CICADELLINAE: PART 2. NEW WORLD CICADELLINI ew 
concave, disk without sculpturing, not pubescent; scutellum not striate behind 
' transverse sulcus. Forewing with membrane including all of apical cells and 
apical portions of anteapical cells, veins elevated and very distinct, with four 
apical cells, the base of fourth more proximal than base of third, claval veins 
approximate near their midlength, without an anteapical plexus of veins, tex- 
ture coriaceous and without sculpturing; forewings of female in rest position 
exceeding apex of ovipositor. Hindleg with setal formula 2:1:1 or 2:1:1:1; 
length of first tarsomere approximately equal to combined length of second 
and third tarsomeres and with two parallel longitudinal rows of small setae on 
plantar surface. 
Male genitalia: Pygofer greatly produced and narrowed, strongly convex at 
apex, setae numerous, located on posterior half. Plates short triangular, not 
extending posteriorly nearly as far as pygofer apex, with multiseriate macro- 
setae and also with microsetae. Style not extending posteriorly beyond apex of 
connective, apex directed mesad. Connective broadly Y-shaped. Aedeagus 
without processes. Paraphyses asymmetrical. 
Female abdominal sternum VII elongate, gradually tapered almost to apex, 
then abruptly narrowed to median apical short truncate process. Ovipositor 
with second valvulae broadened in apical two-thirds, the expanded portion 
bearing convex primary teeth which have weak irregular secondaries, with 
posterodorsal and posteroventral anteapical denticles. 
Specimens belonging to Mucrometopia Melichar have been examined from 
Colombia, Peru, and Bolivia. 
The genus Mucrometopia Melichar is related to Dilobopterus Signoret, from 
which it can be readily separated by the apical cells of the forewing which are 
all much longer and more slender in Dilobopterus. The meron of the hindleg is 
never exposed with the forewings in rest position in Mucrometopia. The yellow 
markings of the forewing of the type-species of Mucrometopia are also sug- 
gestive of the group of Dilobopterus species near fenestratus, n. sp. 
Melichar placed Mucrometopia as a subgenus of Oncometopia from which it 
varies in a great many respects. However, M. caudata (Walker) does have 
some characters suggesting a fairly close relationship to the Proconiini, e.g. 
the face is pubescent beneath, and the hind tibiae are not flattened as much 
as in most Cicadellini. 
The genitalia of the holotype of Tettigonia caudata Walker agree well with the 
illustration published here. A specimen compared with the lectotype of On- 
cometopia peruviensis Distant also had genitalia like the present illustration. The 
synonymy has been previously published by Schréder (1962a:164).
